During an Office 365 migration from an Exchange on-premises, it can be usefull to migrate contacts information. For some reasons, if you can not do a Active Directory synchronization, contacts information needs to be imported manually.

You can easily do that by running two scripts, one in your Exchange environnement which creates an csv file, and the other into the Office 365 Powershell.

During an Office 365 migration, it can be useful to set the regional configuration before the user logon the first time.

Specify the regional setting prevents the user to register the language and time zone again. Moreover, when you want to import PST files into the new office 365 Mailbox, default folders must have the same name. Otherwise you will get two folders for each default folder, like inbox, Sent, Drafts…

Regional configuration

This modification can be done using the Office 365 Exchange cmdlet or we can use a powershell script. Let’s see how to do that.

With an Office 365 business subscription, Microsoft provides a new service in order to make the migration easier: ImportFile. This service allows us to import PST files into Office 365 mailboxes with a web interface. For the moment, you can use it for free, but it will be available for purchase later in 2016.

However, if you try this function without prerequisites, you will get an error for each mailbox. On the status page, you will see this error: Please add Mailbox Import Export role for user running Import and check back in 60 minutes.
